Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm Max length : 7.6 cm SHL 雄魚/尚未辨別雌雄; (Ref. 78146)
Equivalved, oval in shape. Size range: 2.8-7.6 cm shell length. Shell length to height ratio = 1.16 (Ref. 78148). Shell depth reaching 70% of height (Ref. 78152).
In the USA, this species remains a potential fishery resource. From the late 1990s to early 2000s, wild stocks of this species are the target of a small-scale fishery in North Carolina (Ref. 78154) and the eastern coast of Virginia with exports primarily as ethnic food to Chicago, New York, Los Angeles and Washington D.C. (Ref. 78152).
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Sexes are separate with low incidence of hermaphrodism (2.17%). Males dominant (m/f=2.68). Peak in gonadal pattern in late spring to early summer (45% ripe in May) and a minor peak in winter (21% ripe in December). Dribble spawning likely strategy to extend spawning period and increase reproductive success.
